[0002] Plastic materials, also known as plastic raw materials, are polymeric materials primarily composed of synthetic resins. They can be molded into specific shapes under certain temperature and pressure and maintain those shapes at room temperature. They are composed of various components, including synthetic resins and potentially additives such as plasticizers, stabilizers, lubricants, fillers, and colorants. These additives improve the properties of the plastic materials, making them more suitable for actual production and use.

[0003] In existing technologies, the production of plastic materials requires the removal of internal air bubbles. The equipment typically includes a vacuum pump and vacuum piping. The vacuum pump, connected to the top of the barrel via the vacuum piping, reduces the air pressure inside the barrel. When the plastic material is heated and stirred inside the barrel, impurities may be generated, such as small particles and dust produced by plastic decomposition. These impurities are drawn to the vicinity of the vacuum piping along with the air bubbles. If these impurities enter the vacuum pump, they may damage its components. Utility Model Content

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1, as Figures 1-5As shown, this utility model provides a plastic material bubble removal device, including a tank 1, a top cover 3 on the top of the tank 1, a filter tube 4 through and fixedly installed on the top of the top cover 3, a vacuum pump 6 on the top of the top cover 3, a vacuum pipe 5 fixedly connected between the vacuum pump 6 and the filter tube 4, a placement port 18 through the outer wall of the filter tube 4, a filter screen 19 slidably installed inside the placement port 18, a collection box 20 at one end of the filter screen 19, a connecting groove 26 at the bottom of the filter screen 19, and a storage groove 27 on the inner wall of the filter tube 4. A threaded hole 28 is provided through the inner wall of the filter tube 27. A threaded rod 29 is threadedly connected inside the threaded hole 28. A connecting block 31 is fixedly installed on the top of the threaded rod 29, and a handle 30 is fixedly installed on the bottom of the threaded rod 29. A support plate 21 is fixedly installed on the outer wall of the filter tube 4. A first spring 22 is fixedly installed on one end of the support plate 21, and a baffle 23 is fixedly installed on the other end of the first spring 22. A groove 24 is provided on the outer wall of the baffle 23. A limit rod 25 is fixedly installed on the end of the baffle 23 near the support plate 21. One end of the limit rod 25 is slidably inserted into the support plate 21.

[0024] The overall effect of Embodiment 1 is as follows: when bubbles enter the filter tube 4, impurities are filtered by the filter screen 19 and finally fall into the collection box 20. When there are too many impurities, the operator rotates the handle 30, the threaded rod 29 rotates, and the connecting block 31 moves away from the connecting groove 26. Then the operator pulls the baffle 23, the baffle 23 moves away from the placement port 18, the first spring 22 is compressed, and then the operator pushes the new filter screen 19 into the placement port 18 from the other end of the placement port 18. The new filter screen 19 pushes the old filter screen 19, so that one end of it moves away from the placement port 18, and the operator can then remove the old filter screen 19. At this time, the elastic force of the first spring 22 pushes the baffle 23 to reset. When one end of the new filter screen 19 contacts the baffle 23, the connecting groove 26 moves above the connecting block 31. The operator rotates the handle 30 in the opposite direction, and the connecting block 31 enters the connecting groove 26, thus completing the installation and improving the filtration efficiency.

[0025] Example 2, as Figures 1-5 As shown, further, two connecting plates 7 are symmetrically installed on the outer wall of the top cover 3, and an insert plate 32 is fixedly installed at the bottom of the connecting plate 7. A slot 38 is opened through the outer wall of the insert plate 32.

[0026] Furthermore, two fixing plates 8 are symmetrically installed on the outer wall of the tank body 1. The top of the fixing plate 8 is provided with a slot 33. The inner wall of the slot 33 is provided with a limit groove 34. An electromagnet 35 is fixedly installed on the inner wall of the limit groove 34. A second spring 36 is fixedly installed on one end of the electromagnet 35. A locking block 37 is fixedly installed on one end of the second spring 36.

[0027] Furthermore, a sealing groove 16 is provided on the top of the tank body 1, and a sealing ring 17 is fixedly installed at the bottom of the top cover 3 to improve the sealing performance and prevent external dust from entering the tank body 1.

[0028] Furthermore, a feed pipe 9 is installed through and fixedly mounted on the top of the top cover 3, and a pipe cover 10 is provided on the top of the feed pipe 9. A discharge pipe 11 is installed through and fixedly mounted on the bottom of the inside of the tank body 1, and a solenoid valve 12 is provided at the bottom of the discharge pipe 11.

[0029] Furthermore, a motor 13 is fixedly installed at the bottom of the tank 1. The output end of the motor 13 enters the tank 1 and a rotating shaft 14 is fixedly installed thereon. Multiple sets of evenly distributed stirring rods 15 are fixedly installed on the outer wall of the rotating shaft 14.

[0030] Furthermore, three evenly distributed support frames 2 are fixedly installed at the bottom of the tank body 1 to support the entire device.

[0031] The effect achieved by the entire embodiment 2 is that during cleaning, when the staff activates the electromagnet 35, the iron block 37 is attracted away from the slot 38, and the staff can then pull out the insert plate 32 and remove the top cover 3, thus cleaning the inside of the tank 1 and improving cleaning efficiency.

[0032] Working principle: During use, the operator opens the pipe cover 10, introduces the raw material into the tank 1, closes the pipe cover 10, and then starts the motor 13. The output end of the motor 13 drives the rotating shaft 14 to rotate, which in turn drives the stirring rod 15 to rotate, thus stirring the plastic material. During the stirring process, the plastic material is agitated, and the air bubbles are carried to the upper area of ​​the tank 1. Then, the operator starts the vacuum pump 6 to reduce the air pressure inside the tank 1. In a vacuum environment, air bubbles in the plastic material expand due to the internal and external pressure difference. With the aid of stirring, the air bubbles rise rapidly and enter the filter tube 4. After being filtered by the filter screen 19, the impurities finally fall into the collection box 20. When there are too many impurities, the operator turns the handle 30, the threaded rod 29 rotates, and the connecting block 31 moves away from the connecting groove 26. Then the operator pulls the baffle 23, which moves away from the placement port 18. The first spring 22 is compressed, and then the operator pushes the new filter screen 19 into the placement port 18 from the other end. The new filter screen 19 pushes the old filter screen 19, causing one end of it to move away from the placement port 18. The operator can then remove the old filter screen 19. At this time, the elastic force of the first spring 22 pushes the baffle 23 to reset. When one end of the new filter screen 19 contacts the baffle 23, the connecting groove 26 moves above the connecting block 31. The operator then turns the handle 30 in the opposite direction, and the connecting block 31 enters the connecting groove 26, thus completing the installation and improving the filtration efficiency. During cleaning, the staff activates the electromagnet 35, and the iron block 37 is attracted away from the slot 38. The staff can then pull out the insert plate 32 and remove the top cover 3, thus cleaning the inside of the tank 1 and improving cleaning efficiency.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
